I went from a Fastway e2 (step down from the Equal-i-zer 4-point hitch) to an Andersen for a couple of reasons...
- I was having problems with the brackets on the trailer staying in place, I suspect it may have been due to the L brackets that hold the bars in place getting stuck at an angle and then popping during turning which had enough force to also cause the brackets to shift. Doesn't seem to be a common problem so not sure why I had this happen multiple times during our trip this summer.
- The hitch head is heavy and I have a back injury that is easy to aggravate if I lift/turn wrong, then I pay for it for 1-2 days.
- Adjusting the e2 isn't all that fun to get it just right.
- With the e2 I was experiencing a bit of jounce over certain bumps and bridges/overpasses on the freeway.
The Andersen is light, easy to hook up, silent, and easy to adjust to get the weight transfer just right for each trip if needed. To me it also feels like the truck and trailer work more as one unit and I have less jounce. Hard to say if the sway control is any better or worse than the e2, I have the red cone with my Andersen (They have changed cones over time which changes the friction/sway/wear). I never had sway problems or white-knuckle experiences with wither one, but I feel like the Andersen with the red cone may not be quite as good in the anti-sway department.
There are a lot of good hitches out there with a lot of different prices and various advantages and disadvantages. The experience also depends a lot on the tow vehicle and trailer combo, you could have the best hitch and have a poor towing experience if the vehicles aren't a good match, similarly you could have the worst hitch and a great towing experience (Think HD pickup and smaller trailer).
Lots of variables to consider, good luck!
